Product Description:

MHD093C-035-PG1-AA is a Bosch MHD series servo motor. It is a synchronous motor: the motor shaft speed is synchronized to the input current frequency. Other features of the motor are support for digital servo feedback, power connection on side A of the housing, electronic commutation, life-time lubricated bearings, and IP65 rated housing. MHD motors support an optional holding brake. The MHD093C-035-PG1-AA motor is equipped with a 22 Nm holding brake. Rated voltage for the brake is 24 Volts DC and the rated current is 0.71 Amps. Moment of inertia of the brake is 0.00036 kg m2. The connection time is 25 milliseconds and the disconnection time is 50 milliseconds. Mass of the holding brake is 1.1 kilograms. The MHD093C-035-PG1-AA motor has a plain shaft with shaft seal. The IP65 rated motor housing provides robust ingress protection.

Operators can operate the motor with either convection cooling or surface cooling. The continuous torque at standstill is 23 Nm with convection cooling and 34.5 Nm with surface cooling. The continuous current at standstill is 18.3 Amps with convection cooling and 27.8 Amps with surface cooling. The rated motor speed is 2500 RPM with both cooling methods. The rated torque is 9.1 Nm with convection cooling and 26.2 Nm with surface cooling. The rated current is 5.2 Amps with convection cooling and 14.9 Amps with surface cooling. Power output of the motor is 2.9 kilowatts with convection cooling and 8.5 kilowatts with surface cooling. Moment of inertia of the motor rotor is 0.003 kg m2. Mass of the motor is 23.5 kilograms and the size of flange is 140 millimeters. Only trained and experienced technical personnel should handle the motor.

Typical drive / motor fault code	What it means	Practical corrective action
F218 – Amplifier heatsink over-temperature	Power stage in the drive exceeded ≈ 95 °C and shut down to protect itself	Let the unit cool, clear dust from fins, check cabinet airflow, verify fan operation.
F219 – Motor over-temperature	PTC/NTC inside the stator tripped at ≈ 155 °C	Reduce mechanical load or duty-cycle, confirm ambient ≤ 40 °C, inspect blower path.
F220 – Bleeder resistor overload	Dynamic-braking resistor overheated during regen decel	Lengthen decel ramps, add a larger or forced-air bleeder, check wiring.
F221 – Motor-temperature monitor defective	Temp-sensor circuit open/short → supervision lost	Megger PTC leads, repair cable breaks, replace sensor if resistance is wrong.
F226 – DC-bus undervoltage	Link voltage dropped below safe minimum	Inspect mains fuses and wiring, stabilise supply, check supply/regen modules.
F230 – Encoder 1 max-frequency exceeded	Motor encoder signal frequency above interface limit (overspeed or noise)	Verify speed parameters, check for runaway axis, replace damaged feedback cable.
F234 – Emergency-stop activated	+24 V removed at E-Stop input; drive executed controlled stop	Trace E-Stop chain, restore control voltage, reset safety relay.
F236 – Excessive position-feedback difference	Two feedback channels deviate beyond window S-0-0391	Realign external encoder, tighten couplings, set correct resolution parameters.
F242 – Encoder 2 signal too small	Optional external sin/cos amplitude < 1 V	Re-route or replace cable, improve shielding, verify 5 V/12 V encoder supply.
F401 – “Double MST” SERCOS loss	Two consecutive master-sync telegrams missing; drive shut down	Clean fibre-optic links, check light attenuation < 12.5 dB, reseat SERCOS boards.
